Abstract:ν0 derived by sectionalized fitting is erroneous when seismic velocity shows sectionally linear increase with depth, This way of deriving ν0 not only makes ray path and wavefront distorted but also causes t--z curve disjointed, The calculated data prove the existence of the disjointed phenomenon.Translation of coordinate axes can eliminate the disjointed phenomenon on t--z curve. It is pointed out that βmay be negative and the neglect of negative βwill bring fault.
